command line params not available on windows

Running PR268 (maybe also other versions) on windows has the effect of terminating immediately D-Rats:

while the same works on macOs:

(d-rats4) maurizio@Mao-MacbookAir D-Rats-PR-268 % ./d-rats.py --help
INFO:MacOSXPlatform:Forcing DISPLAY for MacOS

                 [--sdebug]

options:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Use alternate configuration directory (default:
                        /Users/maurizio/.d-rats-ev)

The --sdebug option works. The --help and --version options do not work on msys2 mingw64.
I have not tried the other options yet.
